i have had one bo1 and i'm on my third bo1a. very pleased with grp engines so far! holds a tune very well, easy to tune. i can get 10:50 on a tank running under 260*f with a nice stream of smoke! i run on a small track, but thats the best mileage i have had out of a .21, by far. i consistantly break 10:30 with a "safe" tune. these times are also from a bone stock engine!

I don't think the Team GRP drivers were running
stock,out of the box motors. So, lets have a modders
contest. What modder can get the most out of the
.21 and .28 GRP motors? Grindfest '08,be there!

With one weekend of testing I increased runtime on a 7 port by 1:30 minutes in vegas over stock.... just takes some knowledgable tuning, nothing special.... I doubt an out of the box 'any' motor would make the 11+ minutes you have to run in vegas to go without a pit.

There's dozens of variables that play into the runtime external of the engine...driver has a ton to do with it

I've got well over 10 mins on a 50+sec/lap open tracks all over the country with my Vspec...and thats at a good tune, not leaning it to meltdown. There's no 'miracle' engine, never has been, never will be. Practice tuning with a bit leaner bottom than most, a low idle and you'll find your not at WOT nearly as much as running a rich bottom / lean top like most everyone runs.

did i say one word about grp engines being the only engines that this was done to maximo ? holy smokes man , why so defensive ? more of a statement about how they tune their engines in the super fast guy level .

thanks tony!!! but there are magic pipes !!!

Haha Monty I bet

Hoping to get up there for the Hank this year, man that race is a blast

So far, I have tuned an O.S. Speed .21 AL to 12 minutes of run time. I was surprised to get that time. When the car came in, I flipped the car upside down and no fuel in the tank. It shut off a few seconds afterwards. Temps was about 223F. This was at the Hurricane Raceway track. The same one used for the J Concepts RC Clash race.

Matt, I was under the impression that the new GRP line was going to be similar internally to the MR Ninja line but have a few extras that the mario rossi tuned versions had. Otherwise it's a pretty good price increase going from the Ninja for $280 to $420 for the GRP mill just because there name is on it. I'll most likely be picking one of these up this race season at some point.

Thats $420 with pipe and manifold mind you.

well its loud and clear your a die hard Nova fan.... so I figured you were taking shots at the GRP motors...i guess I was wrong my bad !!!

All this buzz about GRP motors. No dough they can build a quality motor! (And apparel) But there (GRP) strategie in signing up (paying) many top drivers to use there motor, is there biggest aset....:sneaky:


What wins on Sunday, sells on monday.........:nod:

Smart on GRP...

got that right :nod: advertisement paying off at its finest :D

Nope, $400 for the motor and $500 for the motor/pipe combo...

I'm sure he was thinking of something else when he said $420.:smile:

Driver finesse... drivetrain efficiency, tuning ability, weight, tyre footprint, weight transfer under acceleration, aerodynamics, enginge age, fuel type and of course type of engine and colour of G string.

Every little factor adds up in fuel effeciency. Same as the set up doesn't make the driver and a good set up with a bad driver isn't going to go places either i guess.


If i was in the market and had the cash to flash i would be curious to run a GRP next to the new RB which looks pretty sweet.
